' Application filed March 4, 1891. Serial No. 383,783. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD R. WILLIAMS, of Syracuse, in the county ofOnondaga, inthe State of New York, have'invented new and usefulImprovements in Elevators, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in elevators, and has for itsobject the production of a strong, automatic, and simple device that maybe readily mounted in operative position and is effioient in operationand durable and convenient in use; and to this end the inventionconsists, essentially, in an elevator-door, an actuating-wheel,connections be tween the Wheel and door, whereby'the move-' ment of theformer opens and closes the latter, and bearing faces or bars on theelevatorcar, movable toward and away from the wheel and adapted toengage opposite points on its periphery for rotating the same reversely.

The invention furthermore consists 'in a hinged support for the faces, aconnection between said faces for operating both simultaneously, and inthe detail construction and arrangement of the parts, all as hereinaftermore particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanyingdrawings, forming a part of this specification,in which like lettersindicate corresponding parts in all the views.

Figure 1 represents a transverse sectional view of an elevator-wellhaving my invention shown in operative position. tical sectional viewtaken on line 2 2, Fig. 1. Fig. 3 is a detail elevation representing aportion of the elevator well and elevator-car, showing the elevator-dooras open and its actuating-wheel and the bearing-faces on theelevator-car as in their position assumed when the door is open. Fig. 4cis a similar view to Fig. 3, illustrating the elevator-door as closed.Fig. 5 is a transverse sectional view taken on line 5 5, Fig. 2. Fig. 6is a transverse sectional View taken on line 6 6, Fig. 3, illustratingthe actuating-faces secured to the elevator-car as in their inoperativeposition. Fig. 7 is a similar sectional view illustrating theactuatingfaoes on the elevator-car as in operative engagement with thewheel for opening and Fig. 2 is a verclosing the door. Fig. 8 is adetail view of the catch for holding the ways in their adjustedposition. Fig. 9 is an elevation of a portion of the elevator-door andthedrum upon which it is wound. Fig. 10 is a detail view,partly insection, representing a yielding extremity provided upon one end of oneof the bearing-faces. Fig. 11 is a detail view illustrating the adjacentedges of two of the slats composing my elevator-door. Figs. 12 and 13are respectively edge and face views of a modified construction of myinvention; and Fig. 14 is a sectional view taken on line 14 14, Fig. 13.

' A represents the elevator-well, having suitable guides B, and O theelevator-car, all of which parts may be of any desirable form, size, andconstruction. The elevator oar illustrated consists of the floor a,central uprights 0', and the cross or tie bar a", suitably braced withthe uprights by bars 0 D represents an upright plank firmly securedalong the side edge of one of the uprights 0, being held at its upperextremity by the angle-brace d, having one arm secured to said plank andthe other arm to the tiebar 0 and'atits lower extremity by the socket orother desirable fastening means (1'.

Projecting from one side a of the well A, with its face in closeproximity to the plank D, is an actuating-wheel E, which is mounted on aspindle e, journaled in a suit-able bearing e, secured by bolts 6 to theside of the well, and is provided with a yielding peripheral face.

F represents the doorway,and G the door for opening and closing saidway. As preferably constructed the door consists of a series of slats gg, secured by rivets 1' to belts r and having on their adjacent edgestongues.

g and grooves g of a curved cross-section. On either or both sides ofsaid tongues or grooves are shoulders g adapted'to firmly support theslats when the door is closed.

pulley or drum G is a cord 71 for rotating the drum G and opening orclosing the door as the wheel E is rotated in reverse directions.

Secured to the plank D and oppositely arranged with each other arebearing faces or bars I, having the lower end of one in substantiallythe same plane as the upper extremity of the other and having the upperextremity of one and the lower extremity of the other supported fromlengthwise movement by the stationary supports 1. Pivoted at oneextremity to the faces I and at the other to a raised rib D on the plankD are links *5, arranged at the opposite extremitiesof each bearing-facefor moving the same uniformly toward and away from the actuating-wheelE.

J represents levers having one extremity pivoted atj to the inner faceof the plank D and the other pivoted to a link or connection J.Projecting from the levers J are pins or lugsj, movable in curved slots9' in the plank D, with their opposite extremities secured to thebearing -faces, whereby upon the movement of said levers thebearing-faces are forced toward and away from each other, in whichmovement the faces are held perpendicular by means of the links 1' i. Tofacilitate yided with a hand-engaging portion j this movement of thebearing-faces, one of the levers J, and preferably the lower one, isprogagement of the upper bearing-face I with said actuating-wheel. Asthe elevator-car continues its upward movement the lower actuating-faceengages at the opposite side of the periphery of the actuating-wheel andreversely rotates the same, thus reversely rotating the drum G andclosing the door, as shown at Fig. 4.

Should the operator not desire-to vary the position of any of the doorsas the elevator-car moves onward, it is merely necessary to force thehand-engaging portion 3' of the lever J upward, whereupon thebearing-faces I are withdrawn from operative position and fail to engagethe actuating-wheel E.

To prevent too sudden a-return movement of the door should theelevator-car move rapidly and continue its upward movement beyond adoor, I provide one of the engaging faces I with a yieldingly-mountedextremity 1 having an inclined front end and a projecting spindle I atits rear end. This spindle is guided in a socket I and is formed withastop I movable in a slot 1 in said face, and interposed between the topof the Thisface and a shoulder I on said extremity is a spring 1 whichconstantly forces said extremity outward and permits the same to yieldslightly upon contact with the actuating-wheel.

At Figs. 12, 13, and 14 I have shown a slightly-modified form .of myinvention, in which the plank D is movably mounted be tweentwostationary uprights L, being connected thereto by links L, and forcedtoward and away from the wheel E by means of a crank-shaft L Theoperation of my invention will be readily perceived from the foregoingdescription and upon reference'to the drawings.

The parts of my invention are neither intricate nor fragile, but aresimple, large, and strong, and are evidently efiicient in use.

As the elevator-car moves up or down, the door may be either opened orpassed without changing its position, as, is desired. A minimum amountof room is required for the open ing door, and there is absolutely noliability for persons to enter the elevator-well. Moreover, my inventionmay be readily applied to any elevator-car at a minimum cost of expenseand requires absolutely no change in the construction either of said caror of the well, it being merely necessary to attach the door-carryingdrum at the upper part of the doorway, secure the actuating-Wheel andits bracket to the side of the well, and bolt the plank D to theordinary upright of the elevator-car.

Instead of a flexible folding door, a swinging or horizontally orvertically reciprocating door may be opened by the wheel E through themedium of suitable connections not necessary to herein illustrate ordescribe, but familiar to any mechanic skilled in the art. It isevident, however, that the detail construction and arrangement of theparts of my invention may be somewhat changed from that shown anddescribed without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In an elevator, the combination, with an elevator-door, a wheel, andconnections, substantially as described, between the door and wheel foropening and closing the door, of an elevator-car, a stationary support Don the car, movable ways on said support, and links hinged to thesupport and to the ways for moving the ways uniformly toward and awayfrom said wheel, substantially as and for the purpose set forth.
